Terminology Orthosis: A singular device used to aid or align a weakened body part Orthoses: Two or more devices used to aid or align a weakened body part Orthotics: The field of study of orthoses and their management Orthotic: An adjective used to describe a device Orthotist: A person trained in the proper fit and fabrication of orthoses
Slide 3-

Prescription: Prescriptions should include the following items: Patient’s name, age, and gender, Current date Diagnosis Functional Goal, Orthotic description Area covered Flexible or Rigid device Custom or Off-the-shelf Control desired based upon biomechanics of the spine Restriction of sagittal plane motion Restriction of coronal plane motion Restriction of transverse plane motion Precautions Physician name and unique physician identifier number Physician signature, office address, contact phone number.

Objective of Spinal Orthoses Control of Pain limiting motion or weight bearing Provides heat to an area Protection against further injury Limits motion Promotion of healing of fractures Stabilization of vertebral segment Provides stabilization when soft tissue cannot Assistance for muscle weakness Serves as a kinesthetic reminder
Slide 5-

Purpose of Spinal Orthoses Prevention and Correction of Deformities By providing external forces Applying corrective forces to abnormal curvatures 3-point pressure system Reduction of Axial Loading Morris,1961 JBJS Elevated intra-abdominal pressure Reduces the net force applied to spine during the act of lifting a weight from the floor Reduces intradiscal pressure approximately 30% in lumbar spine Postsurgical Stabilization With or without fracture John Redford ,PM&R secrets Chapter 96
Slide 6-

Ideal Orthosis Functional Fits well Light in weight Easy to use Cosmetically acceptable Easily maintained/repaired Ideally locally manufactured Different than the “3H’s”predicing failure Hot, heavy, horrible looking
Slide 7-

Prescription Spinal Orthotics Diagnosis/Indications Goals of the orthotic device Area to be covered Control desired Based upon biomechanics of the spine Restriction of sagittal plane motion Restriction of coronal plane motion Restriction of transverse plane motion Flexible Device vs Rigid Custom vs Off-the-shelf Tenet of Orthotic classical practice “Customized orthoses more effectively limit or control motion better than prefabricated or off-the-shelf orthoses”
Slide 8-

Custom vs Off-the-shelf Tenet of Orthotic classical practice “Customized orthoses more effectively limit or control motion better than prefabricated or off-the-shelf orthoses” More intimate fit with custom Better control of Triplanar Motion with custom Better control of lateral flexion and Rotation with custom Unequal panels from OTS that creates flexion or extension components Rotation not controlled in OTS due to not locking down on ASIS or the rib cage Custom better adjustment for pendulous abdomen Custom more comfortable to wear than OTS Bernardoni: Comparison between custom and noncustom spinal orthoses: PM&R Clinic NA 12(2006)73-89

Efficacy of Cervical Orthoses Agabegi: Spinal Orthoses JAAOS, November 2010, Vol 18,#11
Slide 32-

Summary Best CO All orthoses tend to control flexion better than extension Increasing height of the rigid collar more restricted motion May also lead to increase cervical extension (?undesirable) The halo is the most effective orthosis for use in controlling flexion and extension at C1-C3, followed by the 4-poster brace and then the CTOs CTOs are best for use in controlling flexion and extension at C3-T1, whereas the SOMI is best for use in controlling flexion at C1-C5 The CTO brace is the second best orthosis for use in controlling rotation and lateral bending in the cervical spine The SOMI controls extension less effectively than do other orthoses The halo is the best orthosis for use in controlling rotation and lateral bending at C1-C3 The 4-poster (Halo) brace is slightly better than the CTO brace for use in controlling lateral bending in the cervical spine
Slide 33-

Increased back weakness? Lantz and Schultz, Spine 1986 Increase electrical activity of back muscles when LSO worn Principle effect may be a biofeedback mechanism Pfeifer M, AJPMR 2004 Females with one clinical vertebral fracture caused by osteoporosis and an angle of kyphosis of 60 degrees as measured by stereophotomorphometry. Noted: Significant increase in trunk muscle strength Increase muscular activity while wearing the LSO
Slide 61-

Spino-Med by Pfeifer Wearing the orthosis for 6-mo period, 2 hours per day 73% increase in back extensor strength 58% increase in abdominal flexor strength 11% decrease in angle of kyphosis 25% decrease in body sway 7% increase in vital capacity 38% decrease in average pain 15% increase in well-being 27% decrease in limitations of daily living. Overall tolerability of the orthosis was good no side-effects were reported drop-out rate of 3% was rather low.

Accommodative TLSO Key to good positioning! Enhances mobility base Assists patients with pulmonary compromise Used with fixed position wheelchair, tilt in space, or molded seats
Slide 69-

Idiopathic Scoliosis Milwaukee-style CTLSO
Slide 70-

Biomechanic in Scoliosis Large curves are more readily straightened by elongation Smaller curves are more readily straightened by application of lateral forces Usually placing pad below the apex causing lifting force Supine more effective force of TLSO than upright Key to using bracing at night Elongation of curve Reducing lumbar lordosis more effective in treating scoliosis in lumbar and thoracic spine Reduction of the lumbar lordotic curve at the expense of flattening the thoracic kyphotic curve ( may be problem) Correct coronal plane motion but much less 3-D motion Watts, Bracing in Spinal Deformities 1979
Slide 71-

Corrective TLSO Progressive correction of idiopathic spinal curvatures Supple curves (20°-40°) 20°-30° observe initially, if curve progresses by 5° then brace 30°-40° prompt use of orthosis 40°-50° requires surgery, but orthoses may retard progression long enough to allow further trunk growth prior to fusion Indicated Risser <2 Stabilization of congenital spinal curvatures Prevention of progression Usually same curve beginning and end of use Moe + Winter “purpose of bracing is to “keep small curves from getting bigger, not to make big curves smaller” Used full-time 16-20 hrs/day until skeletal maturity -Optimum is 23 hrs/day
Slide 72-

Risser Sign: Apophysis closes from anterior to posterior
Slide 73-

Spinal Orthotics in Scoliosis Curves w/ apices T-8 or lower may be treated w/ underarm braces Wilmington brace (custom made) Boston brace (prefabricated) High thoracic curves may require the Milwaukee Brace “Metal vertical suprastructure with pelvic foundation” Boston Milwaukee Brace
Slide 74-

Charleston Brace Prescribed for part-time wear, usually 8 hours at night Is designed to ‘unbend’ the scoliotic curve Few long-term follow-up studies
Slide 75-

Boston vs. Charleston Katz: 1996 compared the effectiveness of the TLSO Boston brace versus the TLSO Charleston brace Both were statistically comparable in preventing curve progression and surgery in single curves of 25-35° Boston brace was more effective in treating curves 36-45 ° and multiple curves Watts 1977 Boston not use if apex above T10 or curves greater than 40°
